Kenneth William Krugler commented on FLINK-30112:
-------------------------------------------------

As of https://issues.apache.org/jira/browse/FLINK-30113, I think the docs 
should now be updated to note that both keyed and operator state compression is 
supported.

It would be good to clarify that `execution.checkpointing.snapshot-compression` 
is used for both keyed and operator state compression.

And that there's a change to snapshot format which isn't backwards compatible 
(but is forward compatible), or so I assume?
